Complete responses put PureTech's LYT-200 deeper into blood cancer trials
PureTech announced positive topline data from its Phase 1b trial of LYT-200 for relapsed/refractory high-risk myelodysplastic syndrome (HR-MDS) and acute myeloid leukemia (AML), showing complete responses and favorable tolerability. The company plans to prioritize R/R HR-MDS for further development and engage with the FDA for a potential registration-supporting trial. LYT-200, an anti-galectin-9 monoclonal antibody, demonstrated robust antileukemic activity, including a 45.5% overall response rate in HR-MDS patients.
